SQL Server 2008R2 memory issues

Hi Experts.
I have SQL Server 2008R2 installation,We allocated 102400MB(100GB) Memory out of 128GB Installed.
But Task manager is showing SQL Servr using 104 GB.Please some body let us know why SQL Server uisng more memory more than we allocated.
Please advise next step or recommendations if any
OS :Windows 2008R2 64bit.
DB:SQL Server 2008R2 64bit.
Thanks in advance.

But Task manager is showing SQL Servr using 104 GB.Please some body let us know why SQL Server uisng more memory more than we allocated.
You should not refer to task manager for SQL server memory consumption. Its windows tool it always wont show you correct value.
Please use below query to SQL Server memory utilization
select
(physical_memory_in_use_kb/1024)Memory_usedby_Sqlserver_MB,
(locked_page_allocations_kb/1024 )Locked_pages_used_Sqlserver_MB,
(total_virtual_address_space_kb/1024 )Total_VAS_in_MB
from sys. dm_os_process_memory
100 G limit is put on SQL Server buffer pool. SQL Server can still use memory more than 100 G because few memory allocations for objects like, XML,SQLCLR, Linked server, backup , database mail etc are allocated directly by windows and sys.dm_os_process_memory
does not tracks it. So just relax this is normal
Task manager only show Working set.

SQL Server 2008R2 SP2 Query optimizer memory leak ?

It looks like we are facing a SQL Server 2008R2 queery optimizer memory leak.
We have below version of SQL Server
Microsoft SQL Server 2008 R2 (SP2) - 10.50.4000.0 (X64)
Jun 28 2012 08:36:30
Copyright (c) Microsoft Corporation
Standard Edition (64-bit) on Windows NT 6.1 <X64> (Build 7601: Service Pack 1)
The instance is set MAximum memory tro 20 GB.
After executing a huge query (2277 kB generated by IBM SPSS Clementine) with tons of CASE and a lot of AND/OR statements in the WHERE and CASE statements and muliple subqueries the server stops responding on Out of memory in the internal pool
and the query optimizer has allocated all the memory.
From Management Data Warehouse we can find that the query was executed at
7.11.2014 22:40:57
Then at 1:22:48 we recieve FAIL_PACE_ALLOCATION 1
2014-11-08 01:22:48.70 spid75       Failed allocate pages: FAIL_PAGE_ALLOCATION 1

Last error message is half an hour after the inital Out of memory at 2014-11-08 01:52:54.03. Then the Instance is completely shut down
From the memory information in the error log we can see that all the memory is consumed by the QUERY_OPTIMIZER

On the other side MDW reports that the MEMORYCLERK_SQLOPTIMIZER increases since the execution of the query up to the point of OUTOF MEMORY, but the Average value is 54.7 MB during that period as can be seen on attached graph.
We have encountered this issue already two times (every time the critical query is executed).

Hi,
This does seems to me kind of memory Leak and actually it is from SQL Optimizer which leaked memory from buffer pool so much that it did not had any memory to be allocated for new page.

Can you post complete DBCC MEMORYSTATUS output which was generated in errorlog. Is this the only message in errorlog or there are some more messages before and after it.
select (SUM(single_pages_kb)*1024)/8192 as total_stolen_pages, type
from sys.dm_os_memory_clerks
group by typeorder by total_stolen_pages desc
and
select sum(pages_allocated_count * page_size_in_bytes)/1024,type from sys.dm_os_memory_objects
group by type
If you can post the output of above two queries with dbcc memorystaus output on some shared drive and share location with us here. I would try to find out what is leaking memory.
You can very well apply SQL Server 2008 r2 SP3 and see if this issue subsides but I am not sure whether this is fixed or actually it is a bug.

SQL Server 2012- Memory Leak Issue

Team,
We are running a Mission Critical Application on SQL Server 2012 SP2(11.0.5058) which is configured on Always ON Synchronous mode. Offlate due to heavy development work, Application team have come up with stating memory issues. I have analysed all the areas
and everything looks normal. Please suggest if we have to patch the latest CU4 for SQL Server 2012 SP2.
The checks were performed on the below areas:
- Errorlog, System Logs - No errors reported.
- There are close to 8 Databases hosted on the instances which are all configured for AlwaysON. SQL Server is running on VM Infrastructure and the total physical memory allocated is 96GB out of which SQL is capped for 92GB.
-The Page Life Expectancy is healthy and is showing a greater number. There are no Signal waits either or pending memory grants.
- The writes are more than reads for one of the databases which is flagged with application team. There are no blockings & Deadlocks.
Please suggest me the future course of action and your inputs are much appreciated.
Best Regards,
Sharath

Actual issue is- Application team have reported a memory leak and their builds have significantly slowed down. They suspect that its Database memory leak. However I have verified from database end and gave the above inputs.
The AOAGs are good. I was looking for any pointers whether there are any bugs which is related to memory leaks in SQL Server 2012. I know all of them are addressed with SQL Server 2012 SP2.
Application team has NO idea about SQL Server do they ? And to say SQL Server has memory leak you have to actually prove it did they showed any proof. Its common for application team to say SQL Server is leaking memory because they are unaware about fact
by default SQL Server would take as much memory as possible and would release when SQLOS asks it to do so. This might give sign that it is leaking memory BUT IT IS NOT.
As you already said AOAG is working fine so I am presuming there is nothing much to worry. To monitor memory usage in SQL Server 2012 you can use below counters
SQL Server: Memory Manager-- Target Server Memory (KB)
SQL Server: Memory Manager--Total Server Memory (KB)
SQL Server: Memory Manager- Free Memory (KB)
SQL Server: Memory Manager--Database Cache Memory (KB)

Will Cumulative Update 12 for SQL Server 2008R2 SP2 fix: Warning: Unable to Verify TimeStamp for Path\ProgramName?

Hello,
I had a server crash recently and our outsource hosting tech support suggested applying Cumulative Upade 12 for SQL server 2008R2 SP2 to fix the issue. The exception from our dump file "Warning: Unable to Verify TimeStamp for Path\ProgramName"
is not in the list of hotfixes for this CU. Do you know if this will fix this issue? The CU warns not to apply the CU if your issue id not addressed by the CU. Here is a portion of the dump file with the relevant error:

Thank you,
Steve -

The error message appears to be related to a debug session and not come from the actual crash.
So all I know is that you hade a server crash. I don't even know exactly what that means. Did Windows bite the dust? Or was it only SQL Server?
Assuming the latter, I would expect the SQL Server errorlog to have some information (and that would be ERRORLOG.1 or earlier, since the server have been restarted), but if SQL Server died the output may be incomplete.
There may be also dump files, but as I rarely look into these, I am not sure how to interpret them. But I am quite confident that "Unable to verify TimeStamp..." is not the reason SQL Server went down.
I would suggest the following course:
* If the server is not critical, do nothing. As long as it has onlyl happened once, it has only happened once.
* If the server is critical, open a case with Microsoft if you are not able to figure out the reason yourself. The key here is "Unknown exception - code 000042ac".
* If it happens again, you should absolutely open a case. An important thing here is whether the stack dump is identical or something different. If the stack dumps are identical, you may have hit a bug in SQL Server or the OS, and applying CUs or OS
fixes could help if it is a known issue. If the stack dump is something else, you have ghosts in the machine - that is, bad hardware.

Hi Ychinnari,
Based on your description, you fail to install SQL Server 2008 R2 on Windows 7 SP1.
According to the screenshot, we need to verify that if SQL Server 2008 R2 setup disappears when installing setup support files. If so, please post the error message from SQLSetup.log file of the temp folder for analysis. Click on start->run and
type %temp % and press enter, you will navigate to the temp folder. For more details, you can review this
blog. Also, please help to collect the summary and detail logs, by default, the logs can be found in: C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\Log.
In addition, there are some proposals for you troubleshooting this issue.
1. Ensure that your system meets the
hardware and software requirements for installing SQL Server 2008 R2.
2. Make sure that you install SQL Server 2008 R2 with a admin account, and please choose “Run as administrator” to complete installation.
3. Make sure that previous installations of SQL Server has been uninstalled completely from your computer. For more details, please review the similar blog:
SQL Server 2008 R2 Setup starts and then disappears.
4. Stop any Anti-Virus software when installing SQL Server 2008 R2.

Unable to edit maintenance plan Sql Server 2008R2

Hi All,
I am unable to edit sql server maintenance plan and it is failing continuously from job as well.When I try to open the same the throws an error:
Microsoft SQL Server Management Studio is unable to load this document.:
Error loading from XML. No further detailed error information can be supplied for this problem because no Event objects was passed where detailed error information can be stored. It used to work pretty well in the past.Throws same error when I try to connect
remotely.
Regards
Rahul

Has the MP been developed in SQL Server 2008r2 as well?

SQL Server 2005 Memory Explosions

We have the following configuration:
ESXi 5.1.0 running on three clustered Dell 710 servers
vCenter Server 5.1.0
The clustered servers have a total of 88G of RAM
SQL Server 2005 x86 running on a virtual Server 2008 R2 x64. All databases run fine for several days with memory usage seeming at ~25%. Suddenly, the memory consumption
shoots up to ~98% and we have to reboot the server. This is based on information from the task manager and the measurements in vSphere Client. I understand that the task manager is not an accurate measurement when AWE is active but that’s the best I’ve got
at the moment.
Here's what we've done thus far:
Looked through the logs on the SQL Server and found the following:
In the System log, Resource-Exhaustion-Detected appeared at the same time but the highest memory consumption was services.exe at 125MB. Doesn’t seem to be the culprit.
In the Applications log, started getting MSSQLSERVER errors indicating ‘The Server was unable to load the SSL provider needed to login.’ These errors persisted through the downtime.
In the SQL Server Log File Viewer, we see the following errors, though I’m not sure that they are at all related:
A significant part of sql server process memory has been paged out. This may result in a performance degradation. Duration: 0 seconds. Working set (KB): 4464, committed (KB)
66976, memory utilization: 6%
(About 4.5 hours later) Warning: the available page file has dropped below 4Mb. It is at this point – seemingly – that the memory usage has jumped up to near 100%.
The virtual server has 8G of RAM allocated. However, within the vSphere Client, the Memory Granted and the Memory Consumed seem to be at the same value…meaning that
the consumed value seems to be at 100% under normal operating conditions. Not sure why that is.
If anyone has any recommendations or areas to look, we would certainly appreciate your assistance! Thanks in advance.

I thank you guys so much for the rapid response! Please forgive the delayed response. All of this is on a DoD network and I cannot post to blogs on government machines. I have to go to a private
machine. Below is the information you asked for:
The Max Server Memory is 5.0GB and the Min Server Memory is 0.0GB
I have PerfMon currently running to try and capture as much information as possible.
We are getting a few other errors in the SQL Log that has given me some concern:
Failed Virtual Allocation Bytes: FAIL_VIRTUAL_RESERVE 65536
Memory Manager VM Reserverd = 3673288 KB VM Committed = 55688 KB AWE Allocated = 0 KB Reserved Memory = 1024
KB Reserved Memory In Use = 0 KB
There is also a series of MEMORYCLERK and CACHESTORE errors following
The Server was unable to load the SSL provider needed to login. SSL is used…
o
I presume that this is due to the lack of memory to process these SSL request.
There are indeed several Error: 701, Severity: 17, State: 123
Below is the system information from SQL Server 2005:
Microsoft SQL Server Management Studio                   9.00.5324.00
Microsoft Analysis Services Client Tools                       2005.090.5324.00
Microsoft Data Access Components (MDAC)                6.1.7601.17514 (win7sp1_rtm.101119-1850)
Microsoft MSXML
            3.0 6.0
Microsoft Internet Explorer
8.0.7601.17514
Microsoft .NET Framework
2.0.50727.5477
Operating System
            6.1.7601
I run a query SELECT SERVERPROPERTY(‘edition’); and it shows ‘Standard Edition’ rather than ‘Standard Edition (64-bit).’
We are using Windows Server 2008 R2. I don’t believe that there was an x86 version released but I could be wrong.
I’ve actually looked at enabling the LPIM but we are on a domain that we have no control over and there are GPOs that make it very difficult if not impossible to gpedit but that is something
we can certainly look into with the domain owners if you think it might help.
I just ran the following script in SQL:
Exec sp_configure ‘AWE’
The response is name – awe enabled, minimum – 0, maximum – 1, config_value – 0, run_value – 0
There is no third party software on this server.
The Max Server Memory is set to 5GM
Again, I do appreciate all of your help. Please let me know if I can provide anything further.

How could I create a "Linked Server" link from SQL Server 2008R2 64-Bit to Oracle Database 11.2 64-Bit?

How could I create a "Linked Server" link from SQL Server 2008R2 64-Bit to Oracle Database 11.2 64-Bit?
Let's say the SQL Server and Oracle Database are in the same Company Internet Network.
I have the code, but I do not know how to use it. Such as what is System DSN Name? Where could I get it. What does it look like?
Do I need to install any Oracle Client Software in order to link from SQL Server to Oracle? Or SQL Server has the built-in drivers installed already that I can directly create a Linked Server from SQL Server to Oracle?
I need to know details. Thanks.
USE master
go
EXEC sp_addlinkedserver
     @server  = '{Linked Server Name}'
    ,@srvproduct = '{System DSN Name}'
    ,@provider  = 'MSDASQL'
    ,@datasrc  = '{System DSN Name}'
EXEC sp_addlinkedsrvlogin
     @rmtsrvname = '{Linked Server Name}'
    ,@useself  = 'False'
    ,@locallogin = NULL
    ,@rmtuser  = '{Oracle User Name}'
    ,@rmtpassword = '{Oracle User Password}'

You need an OLE DB provider for Oracle. There is one that ships with Windows, but it only supports very old versions of Oracle. Oracle has an OLE DB provider that you can use. I don't know if it's part of Oracle Client or how it is bundled.
You should not use MSDASQL or any DSN.

SQL Server 2008R2 vs 2012 OLTP performance difference - log flushes size different

Hi all,
I'm doing some performance test against 2 identical virtual machine (each VM has the same virtual resources and use the same physical hardware).
The 1° VM has Windows Server 2008R2 and SQL Server 2008R2 Standard Edition
the 2° VM has Windows Server 2012R2 and SQL Server 2012 SP2 + CU1 Standard Edition
I'm using hammerDB (http://hammerora.sourceforge.net/) has benchmark tool to simulate TPC-C test.
I've noticed a significative performance difference between SQL2008R2 and SQL2012, 2008R2 does perform better. Let's explain what I've found:
I use a third VM as client where HammerDB software is installed, I run the test against the two SQL Servers (one server at a time), in SQL2008R2 I reach an higher number of transaction per minutes.
HammerDB creates a database on each database server (so the database are identical except for the compatibility level), and then HammerDB execute a sequence of query (insert-update) simulating the TPC-C standard, the sequence is identical on both servers.
Using perfmon on the two servers I've found a very interesting thing:
In the disk used by the hammerDB database's log (I use separate disk for data and log) I've monitored the Avg. Disk Bytes/Write and I've noticed tha the SQL2012 writes to the log with smaller packet (let's say an average of 3k against an average of 5k written
by the SQL 2008R2).
I've also checked the value of Log flushes / sec on both servers and noticed that SQL2012 do, on average, more log flushes per second, so more log flushes of less bytes...
I've searched for any documented difference in the way log buffers are flushed to disk between 2008r2 and 2012 but found no difference.
Anyone can piont me in the correct direction?

Andrea,
1) first of all fn_db_log exposes a lot of fields that do not exist in SQL2008R2
This is correct, though I can't elaborate as I do not know how/why the changes were made.
2) for the same DML or DDL the number of log record generated are different
I thought as much (but didn't know the workload).
I would like to read and to study what this changes are! Have you some usefu link to interals docs?
Unfortunately I cannot offer anything as the function used is currently undocumented and there are no published papers or documentation by MS on reading log records/why/how. I would assume this to all be NDA information by Microsoft.
Sorry I can't be of more help, but you at least know that the different versions do have behavior changes.

Services configuration for sql server 2008r2 in a Windows Cluster

Hello,
We have a Windows Server 2008 Cluster with Sql Server 2008r2 installed on node 2; when node 2 fails (we don't still know why, it's a 'bluescreen' long history), the service goes from node2 to node1, but sometimes the services are not automatically activated.
What is the theoretical startup settings for sql services (for the sql and the agent), manual, disabled, automatic... ?
Also, sometimes, the service for the sql server in node2 stops, but we don't know why, and we are not able to see any significant information on the event viewer. How can we trace why Sql Server stopped ?
Thanks !

>What is the theoretical startup settings for sql services
Manual. The cluster will start them.
>How can we trace why Sql Server stopped ?
Look in the SQL Server Log.

Hi Please find the pre-requisites for SQL server cluster installation .
Before Installing SQL cluster we need to have a Windows Cluster with required shared storage space and DTC Service configured in Windows
Cluster.
Be ready with the plan of where the SQL to be installed and where the Database, Log, Temp DB and Backup are to be stored.
If you require SOP for this please share your mail id .i will send the same .
